Manures using and manipulation do not belie of in our conditions to the requirements of sustainable development of agricultural production and country in the content with the EU standards. One of the possible way how to use alternative energy sources is the application of decomposed substrate after continual biogas production and afterwards its complex influence monitoring on hydrophysical, chemical and biological soil parameters. On research bases heavy metals content in soils and plants after biosludge application were determined by the dose of 50 t per ha. On the bases of soil samples analyzation these results were gained: Pb content was lower than the limit value for soils, Cd content was higher than the limit value and increased when compared with control variant, Our next research will be focused on possible elimination methods for lowering of heavy metals mobility in the soil after biosludge and stable dung application, on monitoring of soil pH influence, mould structure and its quality and also of clay elements such as significant elemnts by heavy metals immobilization.
